Is reactance an energy storage parameter

Understanding Power Inductor Parameters

An inductor is a component in an electrical circuit that stores energy in its magnetic field. Inductors convert electrical energy into magnetic energy by storing, then supplying energy to the circuit to regulate current flow. This means that if the current increases, the magnetic field increases. Figure 1 shows an inductor model.

AC Capacitance and Capacitive Reactance

Capacitors store energy on their conductive plates in the form of an electrical charge. The amount of charge, (Q) stored in a capacitor is linearly proportional to the voltage across the plates. Thus AC capacitance is a measure of the capacity a capacitor has for storing electric charge when connected to a sinusoidal AC supply.

AC Inductor Circuits

Inductive reactance is the opposition that an inductor offers to alternating current due to its phase-shifted storage and release of energy in its magnetic field. Reactance is symbolized by the capital letter "X" and is measured in ohms just like resistance (R). Inductive reactance can be calculated using this formula: X L = 2πfL

Energy stored in an inductor. The energy stored in an inductor is due to the magnetic field created by the current flowing through it. As the current through the inductor changes, the magnetic field also changes, and energy is either stored or released. The energy stored in an inductor can be expressed as: W = (1/2) * L * I^2

OverviewComparison to resistanceCapacitive reactanceInductive reactanceImpedanceSee alsoExternal links

In electrical circuits, reactance is the opposition presented to alternating current by inductance and capacitance. Along with resistance, it is one of two elements of impedance; however, while both elements involve transfer of electrical energy, no dissipation of electrical energy as heat occurs in reactance; instead, the reactance stores energy until a quarter-cycle later when the energy is returned to the circuit. Greater reactance gives smaller current for the same applied voltage.
